I have seen this behaviour in 4.3.2 - I ended up with at least 5 interfaces on my VRs. I resolved
it by updating my systemVM template as I recall.

As previously pointed out, Can you please send VR start command, /var/cache/cloud/cmdline
file in VR also /var/log/cloud.log.
These logs helps us to understand where the problem is.
Thanks,
Jayapal
